Résumé:
Alternative substrates can contribute to the increase of macro and micronutrients, helping
to improve the productivity of seedlings, reduce production costs, through the scarcity of
natural resources, there is a growing demand for alternative compounds to be used for the
cultivation of vegetables. The objective of this work was to evaluate the feasibility of
applying organic compounds using brewery residues as alternative substrates, replacing
industrial fertilizers and its influence on the chemical attributes of the soil. For the
elaboration of the compounds, Pilsen type brewery waste was used. Therefore, it is
concluded that the use of brewery residue in the proportions of 15% and 20%, presented
a good absorption of nutrients by the vegetables. As for the feasibility analysis, it is
possible to notice that there was a 5% reduction in the costs with compost, that is, with
the modification of the control formulation by the proposed formulation, we can conclude
with the results obtained that the brewery residue is a viable alternative of
supplementation to the soil, without it affecting productivity.
